Blend the PrimoDì together with the spinach and starch, then add the turkey, adjust salt and pepper, and blend for a few seconds until the mixture is well homogeneous.
If you see that the mixture is too moist to form spinach, add a few tablespoons of breadcrumbs (do not overdo it because otherwise it will be too dry).
With damp hands, form a meatball, flatten it and give it an oval shape.
In a small bowl, pour the flour and water just enough to obtain a batter not too thick.
Dip each spinach in this batter and then dip it in breadcrumbs on both sides. Fry in hot oil on both sides until golden brown.
